Interleukin Production by Human Colostral Cells After In Vitro Mitogen Stimulation

Abstract
Human colostral cells were pulsed with PHA, Con A, or LPS and cultivated in serum‐free medium. The culture supernatants were tested for IL‐1 activity in C3H/HeJ thymocyte assay and for IL‐2 activity on human lymphoblasts. The IL‐1 activity was the highest at the 24th h of cultivation and IL‐2 activity at the 48th h of cultivation.
